A system with pressure sensors (5, 12), transmitters (8, 16, 18) and receivers (10, 21) provided in running shoes (2, 3) that upon the shoes (2, 3) leaving or contacting the ground (14) emit and/or receive respective signals (S1, S2, S3, S4). Signals (S1, S2, S4) are formed which are received by a receiver (21) that is independent of the shoes and which are evaluated in an evaluation unit (23). The distance between the feet (FA) is determined from when a front striding foot hits the ground and the rear foot lifts off based upon the timing between the signals using an approximating formula. From the times and the stride length other values movement characteristics of the user may be determined as well.
